Before you start any CNC project, you need to define the quality standards and expectations clearly. This means specifying the dimensions, tolerances, surface finish, material, and other requirements for the final product. You also need to document the quality standards and share them with your CNC operators and programmers. This way, they will know what to aim for and how to measure their performance.
1/2：For new ordered project, first I should make sure I've already completely understood all the specific requirements from the customer. Then we will have a project meeting with all working departments involved in to communicate the project requirements. While communicating the project requirements, remember that every team member should use the common language.They should indicate the requirements clearly and specifically. For example, use the specific tolerance values instead of a symbol; define the chemical content values requirement instead of a foreign material standard; indicate the anodizing type, color, film thickness range instead the drawing notes like type II, Class 3, etc.
Effective communication with CNC operators and programmers is crucial for maintaining high quality standards. I establish clear, detailed documentation of project requirements and quality standards, conduct regular briefings to align everyone on goals, and create an open channel for real-time feedback and troubleshooting. Utilizing visual aids such as annotated schematics and process flow charts helps clarify expectations. Additionally, I emphasize the importance of collaboration through scheduled quality audits and continuous improvement meetings to address any discrepancies promptly.
No princípio o técnico responsável pelo desenho ou pela CAM já deve ser instruído de acordo com a exigência da empresa tão como ter noções de tolerância, na qual devera ser padronizado de acordo com o trabalho a ser e executado.
When training a new operator you need to explain what is expected and what is the standard first. Standards. Have every program documented clearly and precisely. Set standards on tolerances also, some industries 1/16 of an inch is tolerable, some dont. Elaborate quality expectations, this plays on both the supplier provided material quality and the finished product that was done on the machinery.
Ter um relacionamento com os operadores é um papel fundamental de qualquer programador seja ele ficado em melhorias ou até mesmo para entender sob a ótica operacional, onde estão as oportunidades de aprimorar o trabalho em andamento, atribuir os processos se faz naturalmente uma vez que vocês olham para o mesmo horizonte!
One of the challenges of communicating with your CNC team is the different terminology and jargon that they may use. For example, an operator may refer to a tool offset, while a programmer may call it a tool compensation. To avoid confusion and misunderstanding, you need to use a common language that everyone understands. You can create a glossary of terms and abbreviations that you use frequently and make sure that your CNC team has access to it. You can also use visual aids, such as drawings, diagrams, or photos, to illustrate your points.
You must first make sure you fully understand what is required by your customer, that information needs to be communicated to the shop through not only verbal instructions, but also via an inspection report that comes out with the job, again with clear instructions, on tolerance requirements, the frequency that part inspection needs to happen, and any and all inspection equipment required to complete the inspection. A follow up discussion when the project starts. If the project will be running on multiple shifts, all operators need to have the same discussions and follow up spot checks throughout all shifts. If it is a repeat job, I would also recommend a SOP form be created and kept with the old job and electronically stored with the job.
O melhor e independente do jargão utilizado e ter uma equipe com os conhecimentos técnicos e instruídos que ambas nomenclatura estão de acordo e ter um ambiente na qual possam conversar e se entender mesmo que utilizem forma diferente de se expressar
Standardization. This means setting a formula that is understood and agreed on by everyone. Having a formula will make everything seamless and help everything flow better. It will almost act as a second language to most. Standardization not only helps with CNC machining but can be utilized to make everything in the warehouse run effectively and efficiently.
Comunicação ! Os jargões são facilmente identificados uma vez que voce tenha se ambientado, com a galera! Acompanhar os cortes, sanando dúvidas, perguntando como eles agem em situações específicas. Não há necessidade de criar um glossário, até porque quem programa geralmente conhece profundamente o processo de corte e suas terminologias.
By implementing synergy between both parties and create Standard Operating Procedure. Sticking with standards to ensure new generation of machinist and programmers are alligned.
Feedback is essential for improving the quality of your CNC products and processes. You need to provide feedback to your CNC operators and programmers regularly and constructively. You can use various methods, such as verbal, written, or electronic feedback, depending on the situation and the preference of your CNC team. You should also encourage your CNC team to give feedback to each other and to you. Feedback should be specific, timely, positive, and actionable.
I have always liked the method of keeping data. This data can be the amount of parts built using the CNC or the amount of time a part was fabricated. Sharing this real data with your operato(s) can help them understand the bigger goal and may help them figure out a better way to make those numbers bigger or smaller if needed. Providing feedback is also a two way process. You give feedback to your operators but you should also a feedback from them on how they think it should be since they are the ones operating the CNC on a daily basis.
Os feedback são necessários porém além de ser uma ótima ferramenta é preciso usar com sabedoria, está ação é capaz de moldar positivamente uma equipe inteira, trazer a tona o sentimento de "eu pertenço " motivar e trazer resultados extraordinários a empresa! Porém mal aplicado, devasta uma equipe inteira!
Checklists and Guidelines: Create visual checklists and guidelines that outline quality control processes and key quality metrics. Quality Boards: Set up boards in the workspace to display important quality metrics, targets, and updates.
Quality control tools are techniques that help you monitor and control the quality of your CNC processes and products. Some examples of quality control tools are checklists, charts, graphs, histograms, Pareto analysis, cause and effect diagrams, and control charts. You can use these tools to communicate with your CNC team about the current status, trends, problems, and solutions of your CNC quality. You can also use these tools to identify and eliminate waste, errors, and defects in your CNC processes and products.
Quality control can range from data keeping, measuring at interval times, and or simply knowledge of the product. In the industry I am in, knowing what is tolerable and what is not is sometimes enough to make a decision on whether sending the product or not. Sometimes it does take more like using a digital caliper to check for tolerances.
O controle da qualidade é uma exigência atribuída ao produto, para se ter certeza junto ao cliente que está seguindo de acordo com seus requisitos. Além de ser uma ótima ferramenta de rastreio, manutenção os apontamentos não somente direcionam um excelente produto, como fazem um plano de ação de que deve ser feito na própria máquina e setor.
Develop SOPs: Create detailed SOPs for machining processes that include quality checks at various stages. Training on SOPs: Train all CNC operators and programmers to follow these procedures to maintain consistency in quality.
Training and education are vital for enhancing the skills and knowledge of your CNC operators and programmers. You need to train and educate your CNC team on the quality standards, methods, tools, and best practices that you use in your CNC manufacturing. You can use various formats, such as workshops, courses, manuals, videos, or online platforms, to deliver your training and education. You should also update your training and education regularly to keep up with the latest developments and innovations in CNC manufacturing.
Yes this is a Must, I have learned in the trade that a few senior CNC MACHINIST, they have different strategies of how to machine. It's important to learn from them aswell as teaching the new generation what's needed to come. Vise versa we learn from the younger generation too.
I completely understand the importance of training and education in mastering CNC operations. Having spent two decades in a machine shop, I’ve often felt the lack of structured training programs. Most of my learning has been self-driven or through bits of knowledge passed down from colleagues. It can be challenging to keep up with the latest advancements without proper guidance. Workshops, courses, and other educational resources would definitely be beneficial in enhancing my skills and staying updated in this ever-evolving field.
Old dogs, new tricks, there are always new techniques, keep an open mind and always consider alternatives that you may not have thought of. It’s too easy to get locked into “I know better” but try to remember the latest techniques have a history that must be appreciated in order to understand and fully utilise the technique.
These are all excellent guide lines. We practice an open door policy with our programmers and our machinists. In our shop we work together and openly communicate thoughts, and ideas. We also work to support each other as we try different things some may not have experienced before. An open and supported mindset in the shop builds not only comradary, but also drives quality machining practices.
2/2: In the manufacturing link, the factory should provide a separate production drawing with a specific information breakdown to avoid any errors or missing during the communication process. Usually, such drawings are annotated in more detail than the customer's original drawing, and some dimensions and surface requirements are higher than those of the original drawings. Certainly, it's necessary for the operator and programmer to have train and educate. When talking about a repeat job, we will use an SOP together with all the valid information from the first order. The SOP form is necessary and it would help the whole team to do things efficiently and correctly.
A quality culture is a set of values, beliefs, and behaviors that promote quality as a priority and a responsibility in CNC manufacturing. You need to foster a quality culture in your CNC team by setting an example, recognizing and rewarding excellence, involving and empowering your CNC team, and creating a positive and supportive environment. A quality culture will help you communicate with your CNC team more effectively and efficiently, as well as improve the quality of your CNC products and processes.
Every time, when there is any change or further requirements, please make sure every member involved in should be notified to avoid any potential error or information missing.
Make sure they understand their impact on the bottom line, from a productivity perspective and a quality perspective. If everyone is pulling the same direction it helps tremendously. Too many shop floor people have never had anyone explain anything about the business to them, they think there is such a thing as 'company money' for example.
